PTHREAD_COND_TIMEDWAI... BSD Library Functions Manual PTHREAD_COND_TIMEDWAI...NAMEpthread_cond_timedwait — wait on a condition variable for a specific
amount of time
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
int
pthread_cond_timedwait(pthread_cond_t *cond, pthread_mutex_t *mutex,
const struct timespec *abstime);
DESCRIPTION
The pthread_cond_timedwait() function atomically blocks the current
thread waiting on the condition variable specified by cond, and releases
the mutex specified by mutex. The waiting thread unblocks only after
another thread calls pthread_cond_signal(3), or pthread_cond_broadcast(3)
with the same condition variable, or if the system time reaches the time
specified in abstime, and the current thread reacquires the lock on
mutex.
RETURN VALUES
If successful, the pthread_cond_timedwait() function will return zero.
Otherwise an error number will be returned to indicate the error.
ERRORS
The pthread_cond_timedwait() function will fail if:
[EINVAL] The value specified by cond, mutex or abstime is
invalid.
[ETIMEDOUT] The system time has reached or exceeded the time spec‐
ified in abstime.
SEE ALSOpthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3),
pthread_cond_signal(3), pthread_cond_wait(3)STANDARDS
The pthread_cond_timedwait() function conforms to ISO/IEC 9945-1:1996
(“POSIX.1”).
